What is the population equivalent factor for BOD?

The population equivalent factor for biochemical oxygen demand (BOD) is critical for determining the impact of wastewater from a given population on the treatment system. The correct value is typically recognized as 0.17 lb/day per person. This factor is based on average BOD contributions from the typical household, which helps in estimating the total BOD loading to a wastewater treatment facility based on the population it serves.

By utilizing this factor, environmental compliance inspectors can make informed calculations when evaluating compliance with discharge permits and assessing the wastewater treatment facility's capacity. This estimation assists in ensuring that treatment processes are adequate for effectively handling the organic load produced by the population, hence maintaining environmental standards and protecting water quality.
